Fertilize once every half month after planting. It is best to choose organic fertilizer. The concentration of fertilizer should not be too high. Don't water it temporarily after fertilization. Water it regularly to keep the soil moist. We must pay attention to controlling pests and diseases. Commonly encountered mustard varieties are big leaves, flowers and leaves, cabbage, tumor stalks and other shapes. The yield of Gaixin mustard is relatively reliable, which is higher than other varieties. Topdressing is an important point of high yield, and high yield can only be guaranteed if it is basically done. Leaf mustard leaves are used for fresh food or processing, and the composition of its yield varies with species and varieties.

Nanchong's winter vegetables and Guizhou's hydrochloric acid vegetables are all processed with thick and tender short stems and petioles. Leaf mustard likes cold and humid climate conditions, but it is not heat-resistant and cold-resistant. Autumn sowing is the main method in Liucheng of the Yangtze River, which is beneficial to increase the yield and variety. When deciding the specific planting season, the following factors can be considered. In the south of the Yangtze River, all types and varieties with strict requirements for cold climate are sown in early September and harvested around1February, because the heat and cold tolerance of leaf mustard is worse than that of Chinese cabbage.

Therefore, in the north of the Yangtze River, the sowing time can be later than that of Chinese cabbage, and the harvesting time can be earlier than that of Chinese cabbage. Before the frost, mulberry fields with loose and fertile soil and semi-shading are selected to remove weeds first, and then 2000 kilograms of decomposed organic fertilizer is applied per mu, then shallow excavation is started, and the organic fertilizer is buried in the ground, and then 20 kilograms of calcium superphosphate, potassium chloride 15 kilograms and ammonium carbonate are sprinkled per mu.

After the emergence of mustard, because its stems and leaves are small, water should be sprayed on the border with a sprayer to prevent the stem of mustard from being damaged by pouring water, and keep the soil moist. When mustard grows two true leaves, it is necessary to carry out thinning and replanting, select some seedlings in dense places and replant them in sparse places. There are still many varieties of mustard, so it is very important to choose high-yield varieties. Common varieties have several shapes, such as big leaf type, mosaic type, heart-wrapped type, tumor stalk type and so on. Personally, the more reliable yield is Gaixin mustard, which is higher than other varieties on average.
